The beneficial technical effects of the invention
1) Zirconium phosphate is added in the process of preparing basalt fibers, wherein the zirconium phosphate can improve the crystal structure of the basalt fibers, so that the mechanical properties of the basalt fibers are improved;
2) The elastic polyurethane material is added into the polytetrafluoroethylene, so that the elasticity and the bending resistance of the polytetrafluoroethylene can be obviously improved, but the bending resistance at low temperature is obviously reduced, and the inventor finds that through the treatment of ammonium phosphate, the adhesion of phosphate ions on the surface of basalt can increase the surface roughness of fibers and improve the surface activity of basalt fibers, so that the bonding strength between the basalt fibers and polymers is improved, more active groups are grafted on the surface of the basalt fibers in the subsequent surface treatment process of the sizing agent of the activated basalt fibers, the bonding strength between the basalt fibers and the polytetrafluoroethylene before the polyurethane is improved, and the bending resistance of a fiberboard at low temperature is obviously improved.
3) Compared with other phosphate solutions, the ammonium phosphate solution is nearly neutral, does not corrode basalt fibers, and can ensure the mechanical properties of the basalt fibers;
4) The sizing agent containing the silane coupling agent KH-550 and the polyoxyethylene stearate can be used for grafting a large number of active groups on the surface of the fiber rapidly, so that the chemical bonding capability between basalt fiber and other materials is improved, hundreds or even thousands of basalt monofilaments in basalt coarse fiber can be clustered, and the mechanical property of the basalt fiber is improved.

Experimental effect
Flexural strength testing was performed on an Instron1195 universal materials tester, made in english. The test strips used as tests were 3×4×35 (mm×mm). The span was 30mm and the loading rate was 0.5mm/min as measured by the three-point bending method. Each data was tested for 5 bars and then averaged. According to ISO14704:2000 test examples and comparative examples the flexural strength of basalt fiber boards is shown in table 1.
TABLE 1
Figure BDA0004154440660000101
From the data of the examples, it can be seen that the room temperature and low temperature performance of the fibers treated with zirconium phosphate doping and ammonium phosphate co-treatment remain almost the same; referring to comparative examples 1 to 2, it can be seen that, when polyurethane is added to the composite board of unmodified basalt fiber and polytetrafluoroethylene, although the flexural strength at room temperature is improved, the flexural strength is remarkably reduced in a low temperature environment, and the flexural strength is hardly improved in a low temperature environment as compared with the composite board without polyurethane; referring to comparative example 3, it can be seen that the modification of zirconium phosphate only for the bastard fibers has a partial effect on improvement at low temperature and low temperature, but the attenuation of bending resistance at low temperature is still very remarkable; referring to comparative example 4, it can be seen that the use of the ammonium phosphate activated basalt fiber can significantly reduce the difference in bending resistance at low and low temperatures; as can be seen from comparative example 5, the mechanical properties of basalt are reduced after the surface treatment and activation process using sodium phosphate, probably because the ammonium phosphate solution is alkaline after hydrolysis, which causes corrosion to basalt fibers, resulting in reduced mechanical properties; referring to comparative examples 6-8, when the silane coupling agent KH-550 and the polyoxyethylene stearate are independently acted, the performance is not obviously improved, but the combination of the silane coupling agent KH-550 and the polyoxyethylene stearate obviously improves the bending resistance of the basalt fiber composite board.
While the present invention has been described in detail through the foregoing description of the preferred embodiment, it should be understood that the foregoing description is not to be considered as limiting the invention.
